ベトナムの猛暑対策について

AC + fan layering is national cooling culture — most households combine multiple appliances and pair fans with AC across every income tier, not just budget households.

Electricity bills are the #1 heat anxiety — driving shorter runtimes, multi-device efficiency strategies, and a sharp inverse correlation between income and bill worry.

Young consumers consume cooling; older consumers buy their way out — young people drink more cold beverages, while older consumers take taxis/Grab specifically to avoid heat exposure.

Sunscreen is the sharpest gender divide in the data — women apply sunscreen at far higher rates than men; skin protection remains a female-coded behavior in Vietnam.

Women cover up, men strip down on motorbikes — women ride fully covered against the sun, while men prioritize lightly dressed breathability.

Higher income upgrades gear; lower income adapts the body — wealthy consumers buy sunscreen, taxis, and better clothing; lower-income households take more showers and accept more heat exposure.
